Don’t miss this year’s public Fairbrother lecture on bilingualism, ageing and the brain, at the University of Reading!

Thrilled to announce that our own Toms Voits has been selected to deliver the University of Reading 2020 Fairbrother lecture! The Fairbrother Lecture is a prestigious annual event where a single doctoral researcher from the University is selected to present their research to the general public. This year Toms will talk about his PhD research, focusing on the effects of bilingualism on the ageing brain (see below for a summary of the talk).  

So don’t miss this public event, due to take place on May the 12th, 7 pm, at the University of Reading! This public event is free but booking required, so make sure to secure your tickets. For more info, and to book your free ticket, click here.


Language is frequently in the headlines, from worries about people speaking too many languages or too few, to questions of whether bilingualism protects against cognitive decline in later life. Bilingualism has featured prominently in language debates, with stories often over-simplifying a more complex picture.

Cut to the heart of recent research on brain and language. Follow researcher Toms Voits on a journey through the uniqueness and complexity of the human brain’s capacity for language. This public lecture will introduce the ways in which two or more languages co-habit within a single mind, the processing issues of co-operation and competition between languages which arise from that, and the much-debated effects of bilingualism on mind and brain. With a focus on research on bilingualism in older adults, the lecture will examine some of the complexities that need to be unpicked in order to understand relationships between ageing, cognitive health and language.

Bilingualism affects the structure of the brain in adults. This is indicated by experience-dependent gray and white matter changes in brain structures implicated in language learning, processing, or control. However, limited evidence exists on how bilingualism may influence brain development. We examined the developmental trajectories of both grey and white matter structures in a cross-sectional study of a large sample (N=711 for grey matter, N=637 for white matter) of bilingual and monolingual participants, aged 3-21 years. Metrics of grey matter (thickness, volume, surface area) and white matter (fractional anisotropy, mean diffusivity) were examined across 41 cortical and subcortical brain structures and 20 tracts, respectively. We used generalised additive modelling to analyse whether, how, and where the developmental trajectories of bilinguals and monolinguals might differ. Bilingual and monolingual participants manifested distinct developmental trajectories in both gray and white matter structures. As compared to monolinguals, bilinguals showed: a) more gray matter (less developmental loss) starting during late childhood and adolescence, mainly in frontal and parietal regions (particularly in inferior frontal gyrus pars opercularis, superior frontal cortex, inferior and superior parietal cortex, and the precuneus); and b) higher white matter integrity (greater developmental increase) starting during mid-late adolescence, specifically in striatal-inferior frontal fibers. The data suggest that there may be a developmental basis to the well-documented structural differences in the brain between bilingual and monolingual adults.

Brain plasticity associated with second language acquisition and learning has been a focus of research in the past two decades. Recent research on cognitive neuroscience has enriched current understanding on the neurological underpinning of second language learning. Beyond behavioral findings, examining brain functions and structures provides a biological explanation of how language acquisition (as a natural experience) and learning (as an active skill and knowledge acquisition process) shapes the human brain. Together, combining cognitive neuroscience methods and second language acquisition and learning has offered an opportunity for cross-disciplinary collaboration. To facilitate cross-disciplinary understanding and potential research collaboration, this review paper aims to provide an overview of the major cognitive neuroscience methodologies adopted to study second language acquisition and learning. A selection of empirical studies covers second language acquisition in developing children, bilingualism as a naturally-occurring experience, and short-term second language learning in laboratory settings. Brain structural (diffusion tensor imaging, DTI; and voxel-based morphometry, VBM) and functional (electroencephalography, EEG; and event-related potentials, EPRs) methods are briefly discussed with suggested further readings. The paper ends with future directions using these methodologies to explore brain changes in response to second language teaching and learning experience.

Kick-starting 2020 with a few talks!

The new year has just started, and our lab is already busy with several talks this week! Specifically:

-Christos will deliver a talk at the Ringvorlesung Multilingual Mind at the Department of Linguistics, University of Konstanz, on Tuesday 7/1 at 5 pm. The title will be “The effects of bilingualism on brain structure

-Toms will present a paper at the Experimental Psychology Society (EPS) London meeting on Thursday 9/1 at 12.00. The title of the paper will be “The effects of bilingualism on the structure of the hippocampus and on memory performance in ageing bilinguals

-Toms will also give a talk at the annual conference of the Association for Science Education on Saturday 11/1 at 14.00 . The title of the talk will be “Effects of bilingualism on healthy ageing and dementia

See you there!

New pre-print: Bilingualism and neurodegenerative disorders beyond Alzheimer’s Disease

Voits, T., Pliatsikas, C., Robson, H, Rothman, J.(2019): Beyond Alzheimer’s Disease: Bilingualism and Other Types of Neurodegeneration

Bilingualism has been argued to have an impact on cognition and brain structure. Such effects have been reported in healthy children and young adults, but also in ageing adults, including clinical ageing populations. For example, bilingualism may significantly contribute to the delaying of the expression of Alzheimer’s dementia symptoms. If bilingualism plays an ameliorative role against neurodegeneration, it is possible that it would have similar effects for other neurodegenerative disorders, including Multiple Sclerosis, Parkinson’s and Huntington’s Diseases; however, relevant evidence remains limited. Herein, we provide a focused literature review on the effects of these progressive neurological disorders on cognition and brain structure, examine how the affected functions and brain regions map to those suggested to be impacted by bilingualism, and report the limited evidence of the impact of bilingualism on these conditions. We then examine the value of making links across neurodegenerative disorders and bilingualism, proposing that available evidence warrants claims for bilingualism-related effects more generally, with an eye at future research to fill in gaps in our understanding.

Bilingualism has been suggested to be beneficial for executive control and could have positive long-term effects by delaying the onset of symptoms of degenerative diseases. This research investigated for the first time the impact of bilingualism on the executive control, specifically the monitoring and inhibitory control, in individuals with Multiple Sclerosis (MS), a neurodegenerative disease which commonly causes deficiencies in the cognitive system. Bilingual and monolingual adults, with and without an MS diagnosis, performed a flanker task in two degrees of monitoring demands (high monitoring vs. low monitoring). Results showed that bilingual MS patients had similar inhibitory control and monitoring abilities to healthy bilingual controls. In contrast, monolingual MS patients showed similar inhibitory control but significantly worse monitoring abilities compared to monolingual healthy controls. We propose that the similar behaviour between bilingual groups suggests that bilingualism might counteract cognitive deficits related to MS, especially with respect to monitoring. The high monitoring cost observed in monolingual patients seems related to underlying deficits in the monitoring and possibly switching, executive control abilities commonly impaired in MS patients from early stages. Our findings provide some preliminary evidence for the cognitive reserve hypothesis in bilingual MS patients
